The transformation story of Eczacıbaşı İlaç Pazarlama offices begins with adapting the hybrid system that entered our lives during the pandemic period to their working models. The change in work culture has also started to change habits and practices. The first aim adopted by MUUM was to see the reflection of changing habits and practices in the space. Co-working spaces have been created instead of executive rooms, and space setups have been created that will diversify working scenarios with alternatives instead of a desk dedicated to the employee. A design language has been developed to meet every need in an office space at the most optimum level. In order to increase the comfort in the work area, priority was given to ventilation, lighting and acoustic values.
